Bandwidth Demand at American Universities 392
Robert Rwebangira writes: "There is an article in The New York Times (free reg required), discussing college students 'insatiable demand for bandwidth.' Of particular interest is the continuing prominence of file-sharing (inspite of the demise of Napster) and the amount of bandwidth consumed in even 'legitimate' activities. It seems students demand for bandwidth just keeps growing."

At my big ten University bandwidth use by the residence halls has been enough of a problem to cause our keycard access system to become DOS'd. You need keycards to buy food, enter buildings etc...
As of Monday 1.5 GB a week upload and 1.5 GB a week download restrictions go into place. You get two warnings if you exceed these limits and then your residence hall connection is yanked for a semester.

Of the 40 Mb/s, on average one-half of it would be in use directly by students in the dorms. At times, individual ports would be using 7-8 Mb/s, for as long as ten hours at a time. Eventually, it was decided that the impact on the university's bandwidth was affecting the educational functions of the campus network and all users were reminded by mail of the campus AUP for the network.
Students, being students, ignored it largely. The offenders who chose to ignore it and flaunt the fact they were ignoring it (anything above 2 Mb/s for over a few hours) were warned by mail individually, and after that, had their ports shut off and the MAC address of their computers banned from the DHCP pool, so no matter where they went (i.e., plugging it into their roommate's port), they were locked out. To receive service again, they needed to contact the student judicial affairs, which involved only signing an agreement not to be naughty again, with the threat of being kicked out of the dorms.
Long story short, a few people got their ports shut off and had to go through all the rigamarole. Most of they had no idea what they did was wrong, and didn't understand that leaving Kazaa, Morpheus and all their other file trading utilities on all day long was not only illegal, but the reason they received the notices in the first place.
It boggles my mind to think that these kids got into a university and don't understand that downloading the new N'sync album before it's on store shelves is illegal. Theft is theft, no matter who you're screwing over, but luckily, most will figure it out pretty quickly when the university tells them they were disconnected because Sony contacted the university about their particular computer, and yes, both the university and Sony would be more than happy to have them kicked off campus rather than deal legally with a pirate.

Things to think about in the current suggested solutions:
1. Limiting bandwidth to dorms just hurts students who don't run these programs! Yes there are some of us out here. The majority of students even in a small school can not be organized to stop running this type of software. They just bitch about the slow connection and keep right on downloading mp3's. At least that's what happened when our college tried it.
2. Blocking ports isn't effective. One of the earlier posts mentioned about how Morpheous and others seek out new ports. This makes normal port blocking on a router or firewall useless and may arbitrarily block other software that is not a problem but happens to use the same port. You have to have software smart enough to look at packet type/content to be effective.
3. QoS software works if you get the right package. I work for the computer center at my college and I know we went through a number of packages before we settled on one. But it really makes a difference and it's suprising how many people don't even know this sort of software exists.

Problem is, no one at school wants to hear about the problem; they just accept the collateral damage.
Does anyone know why/if this must be the case? i don't really understand why the software (perhaps Packetshaper as mentioned above) ruins the ping times - shouldn't it just drop enough packets so a TCP connection stays at a slow transfer rate?
Also, shooters generally use UDP to send the state information. I imagine file transfer programs use TCP. Not knowing much about the software, would it be possible to shape TCP connections and not UDP? (this would require reading the header)

What always bothered me most about the campus computer setup was how the Business Administration department got new computers every year while the C.S. department and College of Engineering had to wait every four or five years before they could get new computers.

The system was not put in place to hurt filesharers, in fact, because we had that under control - if you exceeded 2 gigs a week downstream or 500 MB a week upstream you got shut off for 1 week - but because too many dorm computers were getting h4x0red and used for DDOS attacks, and the university was getting blamed. (Just be glad they did this BEFORE WinXP came out.)
There's a happy ending, though. Somebody set up a Neomodus DirectConnect [neomodus.com] hub on a dorm computer, and it spread like wildfire. The university only really pays for bandwidth that leaves the university, right? So now we share files to our heart's content, there's no upload or download restrictions, and the downloads are fast as all hell because they're all within the same organization.

Anyway, we put a packet sniffer on the network - turns out an average of 94% of their 10 Mbps pipe was being consumed by Kazaa traffic (port 1214 for those who are curious). That's a lot.
So, this being a high school (OK, perhaps a privileged one), I can see the bandwidth demand for universities only going up when students such as these finish high school and enter univerisity. Large amounts of bandwidth being readily available is gradually becoming the norm, at least here in North America.

The IT Service, only have a few college rooms cabled up. I had one last term, but not this term. What you get is 10Mb/s but ALL web is forced through a proxy server. This is not transparant, but rather blocking outgoing ports. MSN works if you put in the address of the proxy server, and audiogalaxy will figure out the proxy settings. You can ssh out, and in from/to anywhere, and with port forwarding, this is very useful. The ITS NT machines in the computer rooms, are even worse. You get a VNC server running all the time as a service. I am expecting a visit from the director of ITS dressed in a black suit brandishing a gun.

At my school (Lehigh University), we address bandwidth problems this way...
Each student (each MAC address, really) is allowed to transfer one gigabyte within a 12-hour period. If you go over the limit, you get put in a "penalty box" (basically sub-58k speeds) for a while until your transfer total for the past 12 hours is under a gig. Uploads and downloads are counted separately, and transfers that don't go off-campus don't count at all. One of the university's servers holds a list of what addresses are in the penalty box, and what their transfer totals are.
This is quite effective - it gives each student a reasonable amount of bandwidth, and it only punishes those who actually use too much of it. And our 45mbit internet connection is rarely maxed out.

Yep, that kicked in around the very late 90s (until which point JANet had been charging flat rate, or the University Computing Service had been absorbing the variation, but either way the individual colleges and departments didn't take the hit).
Perhaps slightly surprisingly, it wasn't the zillions of us playing Quake II over the 'net that did it. We were generally responsible enough to avoid doing so at peak times and keep it to the evenings and weekends, and many college computer officers had an informal policy of allowing such use as long as it was fair and didn't disrupt legitimate academic things.
Also perhaps surprisingly, this all predates things like Napster. Mass music interchange wasn't going on then on the scale it was until a few months ago.
What did it was the Warez servers blatantly running on university networks. They knew where they were, of course, and for legal reasons closed them down every now and then. But a certain type of hax0r dudez just kept abusing the system. So, now small groups or individuals get charged, caps are in place, traffic is presumably monitored, yada yada.
Sadly, and as all-too-usual, the irresponsible and downright illegal behaviour of a few has now impacted the facilities available to the rest.

That depends on where you are in the world. In most places Theft is legally defined as taking something which has physical substance. So downlading an mp3 is not stealing, since you are not talking something from someone else - its copyright infringement - of course local laws may vary.
Its possible its just kids in the US, but in Europe is many adults as well. With emphasis on MANY - the time may come when the lawgivers are forced to accept that the times have changed.

Given your prior level of abject cluelessness demonstrated previously I am not suprised. How pray tell are you to establish your much vaunted 'ipsec'tunnel across the perimeter when both the firewalls and inside/outside screening routers are dropping udp/500, GRE & ip protocols 50/51 smartarse ?
No security admin with even a smidgen of competence will allow vpn/gre/pptp/whatever tunnel to traverse perimeter security from the LAN to the internet or vice versa. One might as well throw the damn firewalls away otherwise.
Especially considering how trivial it is to split something like a PPTP tunnel and now have a direct ROUTED connection from a foreign network into the LAN.
Tunnels in any properly designed environment are only allowed to start & terminate in a DMZ, or directly on the firewall where access to/from such tunnels is strictly regulated.
